The direct WiFi connection is an excellent convenience feature on the BlackVue DR900S-1CH and DR900S-2CH. This is not to be confused with the BlackVue Over the Cloud which offers additional features which require internet connectivity. The direct WiFi does not require cellular data as it is just a local connection between the phone and dash cam. You just need the Android or iOS app and a WiFi enabled device to use it.
First, let's cover what's changed between the old DR750S and the new DR900S. According to BlackVue, despite having larger file sizes due to higher bitrate and 4K Quality, the DR750S download speeds over WiFi are faster. The dual-band 2.4-5GHz Wi-Fi lets you download dashcam videos to a smartphone at blazing speed. With BlackVue’s Sub-Stream technology, download “Quick Play” versions of the original videos for even faster review. For anyone coming from an older BlackVue device, it's also important to note that the default password is no longer BlackVue. The new password will be device specific and can be found on a sticker underneath the front camera mount along with your SSID and cloud code. This provides improved security compared to having the same password across all devices, especially when considering WiFi is always on by default.
